Problems solved by technology

[0003] Because the back of the release film of the traditional adhesive PP synthetic paper is very smooth, there will be a slight misalignment of the adhesive PP synthetic paper when the paper is printed, so that the printed pattern will be slightly distorted due to the deviation of the drawing

Embodiment 1

[0019] Add 100g of water, 0.5g of dispersant, 0.5g of defoamer and 0.3g of leveling agent in the stainless steel bucket in turn, place it under the high-speed disperser at 1000r / min and stir for 10 minutes, then add 4g of precipitated silica and 4g of titanium dioxide After continuing to stir at a high speed of 4000r / min under the high-speed disperser for 1 hour, add 100g of glue and stir at 500r / min for 10 minutes to obtain the first product of the coating, then filter the first product of the coating through a 200-mesh screen and add 7g of nitrogen Propidium cross-linking agent to obtain the finished coating, and finally use a No. 10 wire rod to coat the release film surface of the pp backed paper, and dry it in an oven at 60 ° C. After drying, test its smoothness as Smoothness is 421s.

Embodiment 2

[0021] Add 100g of water, 1g of dispersant, 0.5g of defoamer and 0.3g of leveling agent in the stainless steel barrel in turn, place it under the high-speed disperser at 1000r / min and stir for 10 minutes, then add 8g of precipitated silica and 8g of titanium dioxide, Continue stirring at a high speed of 4000r / min under the high-speed disperser for 1 hour, then add 100g of glue and stir at 500r / min for 10 minutes to prepare the primary coating, then filter the primary coating with a 200-mesh screen and add 7g of aziridine Pyridine cross-linking agent to obtain the finished coating, and finally use a No. 10 wire rod to coat the release film surface of the pp backed paper, and dry it in an oven at 65°C. After drying, the smoothness is tested as smooth The degree is 227s.

Embodiment 3

[0023] Add 100g of water, 1g of dispersant, 1g of defoamer and 0.3g of leveling agent in the stainless steel bucket in turn, place it under the high-speed disperser at 1000r / min and stir for 10 minutes, then add 10g of precipitated silica and 10g of titanium dioxide, continue After stirring at a high speed of 4000r / min under the high-speed disperser for 1 hour, add 100g of weak solvent glue and stir at 500r / min for 10 minutes to obtain the first product of the coating, and then filter the first product of the coating through a 200-mesh screen and add 7g of nitrogen Propidium crosslinking agent to obtain the finished coating, and finally use a No. 10 wire rod to coat the release film surface of the pp backed paper, and dry it in an oven at 70 ° C. After drying, test its smoothness as Smoothness is 105s.

Abstract

The invention discloses an anti-slip coating for back-adhesive PP paper, which is characterized in that: the anti-slip coating is coated on a release film on the back of PP paper, and the anti-slip coating consists of 4g-10g of two Silicon oxide, 4g-10g titanium dioxide, 100g water, 0.5g-1g dispersant, 0.5g-1g defoamer, 0.3g leveling agent, 100g glue and 7g aziridine crosslinking agent composition. By coating the finished product with a certain roughness and scratch resistance on the release film on the back of the pp paper, the smoothness of the release film on the back of the pp paper is controlled between 105s-421s, so that during the printing process , due to the existence of a certain roughness, it solves the problem of distortion of the printed pattern caused by deviation when the paper is fed.

Description

technical field [0001] The invention relates to an anti-slip coating for adhesive-backed PP paper and a preparation method thereof, in particular to an anti-slip coating for adhesive-backed PP paper which does not cause slight misalignment when the PP paper is printed and a preparation method thereof. Background technique [0002] Adhesive PP synthetic paper is the most commonly used basic consumable in advertising production. Adhesive PP synthetic paper consists of four components, from the front to the back are coating, PP substrate, glue, and release film. The coating is suitable for Three kinds of ink printing: weak solvent ink, pigment ink and dye ink, among them, the adhesive PP synthetic paper printed with weak solvent ink can be used outdoors without coating; the printing with pigment ink is called waterproof adhesive on the market, and only It can be used indoors; when printing with dye ink, the water-based adhesive is not waterproof, and the coating will melt when ...
